That *particular* widget has been done, with various search and regexp
widgets. But they tend to be done quite badly, with each deverloper
going "ooohhh, shiny!!!" and concentrating on feature addition and
showing off all the cool widgets. Kind of like Gnome, actually.
There's an old, fascinating essay about this by Eric Raymond, called
"The L:uxury of Ignorance", over 10 years ago. Gnome tools tend to
violate most of the guidelines, and the software installation tool
violates these in particular:
11. What does my software look like to a non-technical user who
has never seen it before?
And from the guidelines Eric included from a letter writer's submission:
* Can you gracefully and easily duplicate your tools and
configuration for a similar installation?
* Are there settings you can do from the command line or
hand-editing config files that cannot be done from the GUI?

The GUI's can be handy, especially because yum text output becaumes
difficult to script unnecessary header information and the erratic
newlines for long package names.
